Title:
LAMINATED NONWOVEN FABRIC
Document Type and Number:
Japanese Patent JP3661886
Kind Code:
B2
Abstract:
PROBLEM TO BE SOLVED: To obtain nonwoven fabric excellent in handle and touch in an ordinary use, immediately absorbing a liquid such as water, sweat, etc., when absorbing the liquid, diffusing the absorbed water, sweat, etc., to the opposite side, etc., having neither a wet feeling nor a greasiness feeling.
SOLUTION: This laminated nonwoven fabric is obtained by laminating a hydrophobic layer comprising a hydrophobic fiber, having 0.2d to 3d fineness and 5g/m2 to 40g/m2 weight to a hydrophilic layer consisting essentially of a hydrophilic fiber, having 40g/m2 to 200g/m2 weight, has 0.1g/cm3 to 0.3g/cm3 apparent density, ≤60 seconds water absorption rate from the hydrophobic layer. At least part of the hydrophilic fiber is exposed to the surface of the hydrophobic layer so as to make a difference Δqmax between the maximum heat transfer rate in a wet state and that in a humidity conditioned state measured by a cold feel tester ≤0.045(cal/cm2/sec).
